Ok I have recently bought Kingdom Hearts: Birth by Sleep to play on my PSP 3000. The problem though is it is hacked and I only have 5.03 custom firmware on there. Now my questions are this, is it possible to put 6.20 firmware on there and if it is how do I do it? If it however is not possible should I just count my loses ($40) and obtain the game in another way patched or should I just do the actual upgrade and lose the ability to hack in order to play the game that was a big reason I even bought a PSP? Also I have played many of the games on PSP that I wanted to play not counting PS1 or N64 games on there.
